Marked - P.C. and Kristin Cast (House of Night #1)

So the bad news was that I'd have to move into the House of Night, a private boarding school, known by all my friends as the vampyre finishing school, where I would spend the next four years going through bizarre and unnameable physical changes, as well as a total and permanent life shake-up. And that's only if the whole process didn't kill me.

But the good news was that I wouldn't have to take the geometry test tomorrow.

When sixteen-year-old Zoey is marked by the Tracker, she knows her old life is over. Now she has to leave her friends and family to join the House of Night school, where there's only one subject Zoey needs to study: Vampyre 101.

Of course, there's always a catch, and this one's nice and simple: if you fail, you die . . .
